a
By substituting into the inequality, we can check whether the inequality holds true or not.
Since is less than is not a solution to the inequality.
b
Let's do the same thing again and substitute into the inequality.
The inequality doesn't hold true for Therefore, it's not a solution to the inequality.
c
Let's substitute into the inequality and check its validity.
Since is greater than the inequality is true. This means that is a solution.
d
Let's substitute into the inequality and check its validity.
is greater than so the inequality holds true. This means that is a solution.
